There are no rules against phones in Hogwarts, but they are not commonly used. In the books, the students use owls to send letters home, and they have access to the Floo Network for long-distance communication. There are also some enchanted mirrors that allow for instantaneous communication.

In 2026, phones are absolutely allowed within The Wizarding World of Harry Potter (at both Universal Orlando and Hollywood) for photos, videos, and using the Universal app. However, there are strict "No Phone" zones on specific high-thrill attractions. Rides like Harry Potter and the Forbidden Journey (inside Hogwarts Castle) and Hagrid’s Magical Creatures Motorbike Adventure require you to secure all loose items—including phones—in lockers or secure pockets, as they can easily fall and become dangerous projectiles. For Forbidden Journey, you can carry your phone through the highly detailed Hogwarts Castle queue to take photos of the Talking Portraits and Dumbledore's Office, but you must stow it in the free small lockers located at the end of the line just before you board. A 2026 "pro-tip" is to bring a portable power bank, as the heavy use of the "Interactive Wand" maps and the Universal app for "Virtual Line" reservations will drain your battery by lunchtime.
